The core VFS code is quite happy to allow you to make unprivileged mounts in your own namespace, but the particular filesystem being mounted also gets a veto. I think we're expecting NFS will be patched to allow unprivileged mounts some time. See e.g. https://lore.kernel.org/linux-nfs/aec219339d8296b7e9b114d9d247a71fd47423c5.camel@xxxxxxxxxxxxxxx/ --b.
